Preschool Enrollment Hits Record Levels as States Boost Universal Access

The number of 4-year-olds attending state-funded preschools reached a historic high last school year, with enrollment climbing to 1.8 million children nationwide. This surge has been fueled by states embracing universal preschool access and unprecedented spending of $14.4 billion, according to a comprehensive report published Wednesday by the National Institute of Early Education Research.

State-funded preschool programs now serve 37% of 4-year-olds and approximately 10% of 3-year-olds across the United States. While states added 44,000 students to their preschool rolls, the report’s authors noted that this growth was smaller than the previous year’s increase and highlighted the dramatic disparities in preschool accessibility from state to state.

“If providing high-quality preschool education to all 3- and 4-year-olds were a race,” the researchers wrote, “some states are nearing the finish line, others have stumbled and fallen behind, and a few have yet to leave the starting line.”

California emerged as the biggest contributor to national enrollment gains, accounting for more than half the country’s growth with 25,000 new preschool students. This expansion comes as the state makes every 4-year-old eligible for its “transitional kindergarten” program, known as “TK.” However, California’s rapid implementation has involved trade-offs in quality, with the state meeting only two of the institute’s ten quality benchmarks for preschool programs last year.

Private preschool providers in California have voiced concerns that the public school expansion threatens their businesses by drawing away 4-year-olds who previously would have enrolled in private programs.

“Universal TK is a real win, but it’s also just the start of the work and not the end of it,” said Jessica Sawko of Children Now, a California advocacy organization. She noted that the state is already making progress, expected to meet two additional quality benchmarks in next year’s report by lowering its student-teacher ratio to 10-to-1 and requiring lead teachers to have early education training.

The national report reveals difficult choices states often face when scaling programs quickly or operating with limited funding. Hawaii, for example, meets all of the institute’s quality benchmarks but serves only 10% of its 4-year-old population.

Research continues to demonstrate that high-quality preschool can have lifelong benefits for children, making them better prepared for kindergarten, more likely to graduate high school, and more successful in finding employment as adults. Modern kindergarten classrooms now expect children to arrive already equipped with foundational skills.

“We have a lot of kids who still do not fulfill their potential,” said Steven Barnett, founder and director of the early education institute. “We have evidence — very strong evidence — that preschool programs substantially improved the foundation for later success.”

Beyond educational benefits, some states recognize that free prekindergarten programs boost the broader economy by enabling parents to return to work at a time when private childcare has become increasingly unaffordable for many families.

Heather Sufuentes, now director of elementary education for California’s Chico Unified School District, witnessed the positive impact when her district implemented its transitional kindergarten program. She observed that students who attended arrived at elementary school with greater confidence and often volunteered as class leaders.

“They’re well prepared to transition into that big elementary school setting,” said Sufuentes. Chico has more than doubled its TK seats since 2022.

For parents like Marisol Márquez, a state secretary in Los Angeles, California’s TK program has been transformative. Previously, her daughter attended a free learning center supported by COVID-19 relief funding, but that support was ending. Without the public TK program at 1st Street Elementary, Márquez and her husband, a UPS driver, would have struggled to afford private preschool tuition. The program has also helped identify her daughter’s academic strengths, leading educators to place her in kindergarten classes for math and reading.

“If it hadn’t been for this program, we would have never found that out,” Márquez said.

Despite rising expectations for kindergarten readiness, no state mandates preschool attendance, and access varies dramatically nationwide. A family in Wyoming, which has no state-funded preschool, could move to neighboring Colorado, where every 4-year-old qualifies for part-time preschool at no cost. In Washington, D.C., even affluent families can access two full years of prekindergarten, while neighboring Virginia offers much more limited programming.

These disparities exacerbate inequalities, as wealthier families can afford private preschool regardless of their state’s offerings. In 2024, private childcare centers with preschool curricula averaged annual tuition exceeding $12,000 for 4-year-olds, according to Child Care Aware of America.

Lower-income families may qualify for federal Head Start programs, but enrollment in these initiatives is declining, partly due to staffing shortages. Federal or state childcare subsidies can sometimes help with private preschool costs, but waitlists are growing across the country.

Federal support for early education expansion remains limited and is decreasing. Recently, President Donald Trump stated the federal government couldn’t afford to support childcare while engaged in military conflict with Iran, suggesting instead that “states should pay for it… They’ll have to raise their taxes.”

Interestingly, some Republican-led states have pioneered universal prekindergarten, with Oklahoma introducing such programs in the late 1990s. Alabama and West Virginia have also implemented preschool-for-all initiatives that receive top marks from quality evaluators. Meanwhile, some wealthier, Democratic-led states lag behind in statewide implementation, even as cities in those states forge ahead with their own initiatives.

Georgia stands out as the first state with a universal preschool program meeting all quality benchmarks established by the National Institute of Early Education Research. For Atlanta parents like Rebecca Ellis, whose son John Patrick attends the private Capitol Hill Child Enrichment Center free of charge through the state program, the benefits extend beyond financial savings to impressive social and emotional development.

“They focus so much on just helping kids learn how to calm down, to make friends, to regulate their feelings, to solve problems,” Ellis said. These skills have even translated to home life, with her children encouraging their parents to take deep breaths when tensions rise.

As preschool access continues to expand across America, the challenge remains to ensure both widespread availability and consistent quality, giving all children a strong foundation for future success.
